LOCK.

SPECIFICATION forming part of Letters Patent No. 235,818, dated December21, 1880. l

" Application filed August 11,1880. (Model.)

.To all whom it may concern Beit known that I, JOSEPH SIRUGUEY, of NewOrleans, in the parish of Orleans and State of Louisiana, have inventeda new and Improved Lock, of which the following is a specification. 4

The object of my invention is to provide a new and improved lock whichis so constructed that its key-hole can be adjusted to any desiredposition, thus adapting the lock to be attached to doors havingkey-holes from former locks.

The invention consists in a lock having a large aperture below thetumblers in each side wall of the casing, upon which walls or platessliding plates with key-holes are arranged in such a manner that theycan be moved to and fro until they are in the desired position, and canthen be secured by screws passing through slots in said plates. Theremay be two sets of said plates, one of which has a barrel for aspindle-key, whereas the other has avspindle for a barrel-key, thuspermitting the lock to be adjusted to the use of either kind of key.

In the accompanying drawings, Figure l is a longitudinal elevation of myimproved lock, showing the plate with a barrel for the spindle-keyattached. Fig. 2 is a cross-sectional elevation of the same. Fig. 3 is alongitudinal sectional elevation of the same. Fig. 4 is across-sectional elevation of the lock, showing the plate with a spindlefor a barrel-key attached. Fig. 5 is a partial longitudinal elevationand sectional view of the barrel-key.

Similar letters of reference indicate corresponding parts.

The lockA is constructed with an aperture, B, at or near the center ofthe lock, the length of which aperture is equal to about one-third ofthe length of the look, and the height of which is slightly greater thanthat ofthe height of the key-bit in each side plate, C C, below the boltD and tumblers E.

The side plates, C C, have their lower half, F F, recessed slightly, soas to be adapted to receive the metal plates G, G2, G3, or G4, providedwith a longitudinal slot, H, near the upper edge, and with a marker orpointer, J, near one of the ends. The plate Gl is provided with a splitbarrel, K, to receive a spindle-key, L, and the plate G2 is providedwith a key-hole, M, adapted to permit the end and bit of said key L topass through. The plate G3 is provided with a spindle, N, for abarrel-key, O,

whereas the plate G4 has a key-hole, P, for the said key O, and throughwhich the spindle N passes.

The lower edges ot' the plates G to G4 are beveled inward and fit into acorresponding groove on the lower edge ot' the lock-case. These platesare held to the lock-case by screws Q Q, passing through the slot H andtaking in the plates O O.

The bolt D is provided with a longitudinal slot, R, and one of the sideplates G is provided with a corresponding slot, S, located above theslots H H. A sliding plate or block, T, provided with one or morenotches, U U, t0 receive the end of the key-bit is mounted on the boltD, and can be held in any desired position on the same by means of thescrew V, accessible through the slot S, with which it is on the samelevel. The slot S is provided with a scale or end divisions, as arelikewise the upper edges of the recesses F F, for a purpose that will beexplained hereinafter.

It is often the case that a lock is to be at tached to an olddoor-provided with a keyhole, and it is desirable to have the oldkeyhole in the door and the key-hole of the new lock to correspond inposition. This is obtained with my improved lock, as follows:

It' a spindle-key is to be used, the plates G and G2 are attached to theside plates, O C, being held by the beveled lower edge and the screws QQ. The barrel Kmust pass through the old key-hole, and the plate G2 isthen adjusted so that its indicator J is opposite the saine subdivisionof its scale as the indicator J of the plate G. The notched plate T isthen adjusted in such a position that it is opposite the samesubdivision of its scale as the indicators ofthe plates G and G2.

If a barrelkey is to be used, the plates G3 and G4 are attached to theplates C G in a similar manner, the spindle N being adjusted to t intothe old key-hole, and the plate G4 and the notched block or plate Tbeing adjusted accordingly, as described above.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A lock with an adjustable key-hole made substantially as herein shownand described,

IOO

and consisting of a loclr With sliding key-hole plates and With asliding notched plate or block, in which the end of the bit takes on thebolt, as set forth.

2. The combination, with the lock A, of the plate G', provided With abarrel, K, and a longitudinal slot,H, of the plate G2, provided with akey-hole, M, and a longitudinal slot, H, and of the screws Q Q,substantially as herein shown and described.

3. The combination, with the lock A, provided With a longitudinal slot,S, of the bolt D, provided With a longitudinal slot, 1t, of the slidingplate or block T, provided with notches
